+A Minecraft pathfinder bot.
+
+[**Baritone Discord Server**](http://discord.gg/s6fRBAUpmr)
+
+Baritone is the pathfinding system used in [Impact](https://impactclient.net/) since 4.4. There's a [showcase video](https://youtu.be/CZkLXWo4Fg4) made by @Adovin#0730 on Baritone which I recommend. [Here's](https://www.youtube.com/watch?v=StquF69-_wI) a (very old!) video I made showing off what it can do. [Tutorial playlist](https://www.youtube.com/playlist?list=PLnwnJ1qsS7CoQl9Si-RTluuzCo_4Oulpa)
+
+The easiest way to install Baritone is to install [Impact](https://impactclient.net/), which comes with Baritone. The second easiest way (for 1.12.2 only) is to install the v1.2.* `api-forge` jar from [releases](https://github.com/cabaletta/baritone/releases). **For 1.12.2 Forge, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.2.14/baritone-api-forge-1.2.14.jar)**. Otherwise, see [Installation & setup](SETUP.md). Once Baritone is installed, look [here](USAGE.md) for instructions on how to use it.
+
+For 1.15.2, [click here](https://www.youtube.com/watch?v=j1qKtCZFURM) and see description. If you need Forge 1.15.2, look [here](https://github.com/cabaletta/baritone/releases/tag/v1.5.3), follow the instructions, and get the `api-forge` jar.
+
+For 1.16.5, [click here](https://www.youtube.com/watch?v=_4eVJ9Qz2J8) and see description. If you need Forge or Fabric 1.16.5, look [here](https://github.com/cabaletta/baritone/releases/tag/v1.6.3) and get the `api-forge` or `api-fabric` jar. **For 1.16.5 Fabric, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.6.3/baritone-api-fabric-1.6.3.jar)**.
+
+This project is an updated version of [MineBot](https://github.com/leijurv/MineBot/),
+the original version of the bot for Minecraft 1.8.9, rebuilt for 1.12.2 through 1.16.5. Baritone focuses on reliability and particularly performance (it's over [30x faster](https://github.com/cabaletta/baritone/pull/180#issuecomment-423822928) than MineBot at calculating paths).

+
+# API
+
+The API is heavily documented, you can find the Javadocs for the latest release [here](https://baritone.leijurv.com/).
+Please note that usage of anything located outside of the ``baritone.api`` package is not supported by the API release
+jar.
+
+Below is an example of basic usage for changing some settings, and then pathing to an X/Z goal.
+
+```
+BaritoneAPI.getSettings().allowSprint.value = true;
+BaritoneAPI.getSettings().primaryTimeoutMS.value = 2000L;
+
+BaritoneAPI.getProvider().getPrimaryBaritone().getCustomGoalProcess().setGoalAndPath(new GoalXZ(10000, 20000));
+```
+
+# FAQ
+
+## Can I use Baritone as a library in my custom utility client?
+
+That's what it's for, sure! (As long as usage complies with the LGPL 3.0 License)
+
+## How is it so fast?
+
+Magic. (Hours of [leijurv](https://github.com/leijurv/) enduring excruciating pain)

 The build is fully deterministic and reproducible, and you can verify Travis did it properly by running `docker build --no-cache -t cabaletta/baritone .` yourself and comparing the shasum. This works identically on Travis, Mac, and Linux (if you have docker on Windows, I'd be grateful if you could let me know if it works there too).

 - **Forge Standalone**: Same as Standalone, but packaged for Forge. This should be used when Baritone is your only Forge mod, or none of your other Forge mods integrate with Baritone.
 - **Unoptimized**: Nothing is obfuscated. This shouldn't be used ever in production.
 
-## More Info
-To replace out Impact 4.5's Baritone build with a customized one, build Baritone as above then copy & **rename** `dist/baritone-api-$VERSION$.jar` into `minecraft/libraries/cabaletta/baritone-api/1.2/baritone-api-1.2.jar`, replacing the jar that was previously there. You also need to edit `minecraft/versions/1.12.2-Impact_4.5/1.12.2-Impact_4.5.json`, find the line `"name": "cabaletta:baritone-api:1.2"`, remove the comma from the end, and **entirely remove the NEXT line** (starts with `"url"`). **Restart your launcher** then load as normal. 
-
-You can verify whether or not it worked by running `.b version` in chat (only valid in Impact). It should print out the version that you downloaded. Note: The version that comes with 4.5 is `v1.2.3`.

 ## Build it yourself
 - Clone or download Baritone
